hi amrin, there is no shortcuts in studies if u have then tell it first

There is a powerful method to solve a problem esp.in maths(analytical geo.).
Find answer using options.Substitute the options in the given question to find the answer.Remember this is applicable only when
the option none of these is not there.

KAB

It is applicable only in objective questions.It can also be applied to problems on summation or series.

In indefinite integral when there is no clue to proceed try differentiating options.

This sometimes saves a lot of time.

Well, when you are solving objective questions, there are quiet a few tricks you can use...

Firstly, never use variables unless you have no other option.

so, if you have some problem on an arbit AP, assume the AP as 3,5,7,9.. or anything that agrees with the question.

Secondly, you can always use special cases. For example if the question is about ANY chord of a circle, we can consider the diameter as a chord. Or if we have to take a tangent of an ellipse, it can be X = a or Y = b, etc

Thirdly, if any question is completely symmetrical in X and Y, its answer will also be symmetrical in X and Y( ie X and Y can be interchanged). For example, the pts of intersection of

X² + Y² = 4 and X + Y = 2 are (0,2) and (2,0)

The method of working backwards from the options is also useful. For eg u have to find the indifinite integral of some expression, just differentiate the options and check if u get the intigrand.

And lastly... well memory works a lot in oblective... if you somehow... by practice or otherwise ... already know the correct option... nothing can be better.

But be cautious, these tricks are helpful but YOU WILL HAVE TO APPLY YOUR COMMON SENSE WHILE USING THEM.
